Issue:

When you double-click a text, the program sends an error message:

Unknown command "ddedit"

Causes:

An error may have occurred in the user interface customization when you migrated from a previous version. This happens because the DDEDIT command, which was activated when double-clicking text in the previous versions of the program, was discontinued with the 2015 release.

Solution:

You can correct this problem using a couple of methods.

Update the Customize User Interface dialog box

The corresponding macro can be corrected in the Customize User Interface utility as follows:

1. Type CUI in the command line.
2. In the left window, navigate to "Double Click Actions" > Text > Text, Edit.
3. In the right panel, edit the macro and replace ^C^C_ddedit with ^C^C_textedit.
